In this paper, a new accelerated test method according to the influence of cement temperature and curing age is developed to detect the 28-day cement strength by using the standard test equipment based on weighted maturity theory. The results show the new method can accurately predict 28-day cement strength, which the mean of (predicted value) / (measured strength) is 0.98 and the COV. is 5.95%.
